ELECTRIC BRUSH.

SPECIFICATION forming part of Letters Patent No. 260,718, dated July 4, 1882.

Application filed December 9, 1881.

Too whom it may concern:

Be it known that I, JOHN W. WEAKLEY, Jr., of Bond Hill, in the county of Hamilton and State of Ohio, have invented a new and Improved Electric Brush, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved electric brush to be used for the relief of nervous complaints, 82c.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the upper side of my improved electric brush, parts being shown in section. Fig. 2 is a longitudinal sectional elevation of the same on the line 3/ y, Fig. 1. Fig.3 is a cross-sectional elevation of the same on the line m a", Fig. 2. Fig. 4 is an end elevation of the top plate and the battery and coil thereon. Fig. 5 is a view in elevation of the handle end of the brush.

The brush A has a rubber or other suitable facing, B, held in place by a metahflanged frame, G, and this facing B is studded with metal pins D, passed through it, the pin-heads remainii'ig on the inner side of the facing in the manner in which brushes with metal pins are generally constructed. The back A of the brush is provided with a recess, E, into which a copper or other metal plate, F, is placed to rest on the heads of the pins D, this plate F being held in place by a wooden filling-block, G, fitting in the recess E. v

A top plate, H, is secured on the upper sur face of the back A by means of screws a, and this top plate carries an inductioncoil, J, provided with a core, K, and the top plate, H, also carries a battery, L, composed of a cell, L, of glass, porcelain, or rubber, provided with a screw-cap, L, to which the carbon element N and the zinc element N (or any other suitable elements) are attached, the elements each be- (Model) J, and can be passed a greater or less distance into the coil.

An armature, S, of the kind generally used with induction-machines is combined with the coil J, and need not be described.

The standard P is connected by a wire, U, with the coil J and with a branch wire, V, of the wire U by the metal plate F. The arm T of the coil is connected by a wire, W, with the spring standard P. The coil J is connected with a metal plate, X, on the handle I of the brush by a wire, Y.

The cell L can be removed very conveniently from between the spring standards P P and the standard Q, and if the cap L is unscrewed the elements N N can be removed and any suitable solution or exciting-fluid can be poured into the cell.

The electric circuits are as follows: The current passes from the carbon element N through the pin 0, the spring-standard P, the wire U, the coil J, the arm 1', the spring S, the contactbutton 8, the contact-screw t, the curved arm T, the wire W to the spring-standard P, the pin and the zinc element N. The core K is magnetized and attracts the armature S, causing an interruption of the current as the contact between the button 8 and screwt is broken; but the moment this contact is broken the spring S tears the armature S from the core K, which isdemagnetized at that moment, and a vibrating current is thus obtained. If the plate X on the handle I is in contact with one hand,and if the pins D are brought in contact with the body, the circuit will be closed. and the extra current passes from the coil J through the wire Y to the plate X, the body, the pins D, the plate F, the wires V and U to the coil J. By drawing the regulator R out of 0 the coil a greater part of the core will be exposed and the current will be augmented correspondingly.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the brush A, provided with metal pins D, of the battery L, the coil J, and the metal plate F, resting on the heads of the pins 1) and connected with the battery and coil, substantially as herein shown I00 and described, and for the purpose set forth.

2. The combination, with the brush A, pro

.vided with metal pins D, of the battery L, the

coil J, the metal plate F, resting on the heads of the pins D and connected with the coil, and of the metal plate X on the handle and connected with the coil, substantially as herein shown and described.

3. In an electric brush, the combination,with a battery, of spring-standards for holding it removablyon the brush, substantially as herein 1shown and described, and for the purpose set orth.
